' To all whom, it may concern:

Be it known that I, CHARLES LOUIS HAN- SEN, a citizen'of the UnitedStates, residing at Racine, in the county of Racine and State ofWisconsin, have invented certain new and useful Improvements in FoldingCots, of which the following is a specification, reference being had tothe accompanying drawing, forming a part thereof.

This invention relates more particularly to folding cotshaving metalframes, and its main object is to produce a comparatively light and atthe same time rigid or stable and durable frame for such cots which canbe easily and quickly folded into small compass'or' set up for use, andwhen spread and adjusted for use will be firm and stable and will notaccidentally collapses It consists in the construction, arrangement andcombination of parts as hereinafter particularly described and pointedout in the claims.

In the accompanying drawing like characters designate the same parts inthe several figures.

P

'i- ThQ' fOIding cot framecomprises two side rails, each composed of twosections a, three palrs of legs 6 and c, and two detachable cross or endpieces or spreaders 05.

The-main members of the frame are constructed of comparatively lightsheet metal of angle-form in cross section, preferably with a wideflange w on one sideand a narrow flange y on the other side of anintervenlng web a, as shown in Figs. 6, 7, 8, 9 and 10, for the purposenot only of securing the desired strength and rigidity with as littleweight as possible, but also of facilitating the folding of the frameinto small compass. Some or all of the members may however, be made withbut one flange,'the narrow flange being omitted.

The sections a of the side rails are pivotally connected adjacent totheir inner ends by rivets e with thecross arms of T-fittings f, placedon the inner or upper side of the wide flanges a: of said section, withreinforcing 1 plates g on the outer or under side plates or fittings fat rightangles to the cross pieces or members thereof as shown in Figs.7, 8 and 9. The upper ends of the end legs b and c are pivoted by rivetsh to the inner or upper sides of the wide flanges m of the side rails a,adjacent to their outer ends, so that they can be folded inwardly asindicated by dotted lines in Fig. 6, parallel with the side rails intothe channel or space between the wide flanges on the outer sides thereofwhen they are brought together, as shown in Fig. 5, and can be turnedoutwardly in setting up the cot intopositions perpendicular to or alittle beyond a perpendicular to the side rails, as shown by full linesin Fig. 6. Each of the end legs is connected with the outer end .of theadjacent side rail b a'zbrace i which is pivoted atone end to t e legand connected at the other end with the side railby a link j,

which when the leg is unfolded, lies parallel with the side rail,bearing along its upper edge against the inner side of said rail atitsfree end beyond its approximately flush with the end of said rail asshown by full lines in Fig. 6.

To lock "and hold the side rails spread apart and the duck or canvas topor cover 70 which connects them, stretched taut, and to prevent the cotwhen set up from accidentally closing, the cross pieces or spreaders dare provided. These cross pieces like the other main members of theframe, are made of sheet metal in angle-form, preferably with flanges ofthe same width on both sides. The flange on one side of each cross pieceis formed adjacent to its'ends with transverse notches fitted to engageand interlock limiting the sp with corresponding longitudinal notches Zin the ends of the side railsa as shown in Figs. 2, 6 and 10, thewideflanges of the side rails being cut away as shown in Fig. 10, topermit the ends of the rails to enter the channel of the cross piecewithout unnecessarily increasin the width of the latter. The flange on te opposite side of each cross piece d is formed or provided withinwardly projecting lugs m, which are arranged to engage with the linksj at one end of the cot and to lock and hold them in place with theassociated bracesz' and legs I) and 0 connected therewith, in operativeposition, as shown in Figs. 1, 2 and 6. These detachable cross pieces orspreaders d are made of such width that they will readily fit over themiddle legs 5' and c, as shown in Figs. 3, 4: and 5, when the cot isfolded. One leg'b of each pair has the web, narrow flange and channel ora flange formed on one side thereof at one end and on the op site sidethereof at the other end, or on opposite sides of its pivot connectionwith the other leg 0, as shown in Figs. 2 and 11, the two legs of eachpair being pivotally connected at or adjacent to the center thereof by arivet or pin n.

A plate 0 is folded over and riveted to the webs or flanges on oppositesides of each leg 7), as shown in Figs.,2, 11 and 12, and forms for thehdad of the rivet n which is shoul ered where it passes through the wideflanges of each pair of legs as shown in Fig. 12, so as to hold themclose together. Each leg 0 has the narrow flange, web and channel or aflan e formed on one side thereof only, and hem pivoted on the rivet 11.between the wide ange of the the leg I) and the plate 0, is'thus adaptedto fold into the channels or recesses on the opposite sides and at theopposite ends of the leg I), as shown in Fig. 11. The webs or flanges ofeach leg I) and the overlying folds of the plate '0 are cut away so asto engage with opposite sides or edges of the associated leg 0 and formstops, as shown in Fig. 2, for read or opening of the legs andpreventing collapse of the cot indepen ently of the top or cover is. Theplate 0 serves also as a reinforcement for each pair .ing hems at theends 7 time comparatively lig of legs adjacent to their pivot connectionWith-each other, as well as forming a hearing for the pivot rivet 11 andstops or limiting the spread of the legs.

-The top or cover 72 of the cot, which may be made of duck, canvas, orother suitable fabric, may be fastened to or held in place any suitablemanner, as by on the frame 1n widehems along the sides through which theside rails 11 are inserted, and correspondthrough which the removablecross pieces or Spreaders d are inserted when the cot is set up. The topor cover is cutaway, as shownin Fig. 1, adj acent -to the corners and tothe middle joints, so as not to interfere with the folding and unfoldingof the frame and to prevent injury to the fabric.

In folding the cot, it is preferably inverted as shown by Fig. 3, and,the cross pieces or Spreaders d being detached and removed, the severalpairs of legs I) and c are folded as shown by Fig. 11, thus bringing therail sections a together the cloth top or cover is foldinglongitudinally and hanging loosely below them. The end are then foldedinwardly into the channel or space or outer flanges of as shown byFigs..3, 5 and 6; the cross pieces or Spreaders d are placed over themiddle legs as shown by Figs. 3 and 5, and the sections a of the siderailswith the end legs are folded on the pivots 6 into .place on0pposite sides of and parallel with the middle legs, as shown by Figs.4, 5 and 9. The top orcover k is finally wrapped around the folded frameand preferably secured in place thereon by straps or other fastenings(not shown).

between the wide By the construction of the main members of the frame ofsheet metal in angle-form, and their arrangement as herein shown anddescribed, a strong, ri id and at the same t metallic frame is produced,which can be easily and quickly folded into compact and convenient formfor transportation or storage.
